Accordingly, preferably the light outcoupling surfaces 30a and thus the partition walls 31, 32 are curved, as shown in FIG FIG. 2 easy to recognize. In order to be able to realize this, it is therefore preferably provided that the projecting sections 21 'are curved, namely curved toward the opposite longitudinal side 22.
